3 Claims. (Cl. 222-193) This invention relates to toy guns, and more particularly to a compressed air type of toy gun having smoke-simulating means.

It is among the objects of the invention to provide a toy gun of the spring plunger or compressed air type having therein means for containing a harmless powder, such as talcum powder, for ejection by the compressed air blast created by the gun whenever the gun is operated, which powder-ejecting means is of simple and economical construction, may be applied to an existing gun or incorporated in a gun during manufacture thereof, holds a large supply of powder and dispenses such powder yin small quantities to simulate smoke from gunpowder each time the gun is operated, and is easily replenished or replaced.

Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawing,l wherein:

Figure 1 is a side elevation of a toy gun showing, in broken lines, the position therein of a powder dispenser illustrative of the invention;

Figure 2 is a longitudinal, medial cross-section y on an enlarged scale of the muzzle-end portion of the barrel of the gun illustrated in Figure 1, showing a powder dispenser illustrative of the invention operatively disposed in the gun barrel;

Figure 3 is an end elevation of the muzzle end of the gun barrel illustrated in Figures 1 and 2;

Figure 4 is a transverse cross-section on the line 4-4 of Figure 2;

Figure 5-is a transverse cross-section on the line 5-5 of Figure 2; and

Figure 6 is a view on a reduced scale, similar to Figure 2 and showing a somewhat modified form of powder dispenser.

With continued reference to the drawing, the gun, illustrated in Figure 1, has a tubular barrel I0 attached at its breech end to a stock II and carrying on its under side a slidable forearm I2 connected by pivoted links I3 to the front end of the stock II. A trigger I4 is pivotally mounted in the stock at the breech end of the barrel and is provided with a sear I5. A piston I6 is slidably mounted in the gun barrel and a rod I1 is connected at its forward end to the piston and extends rearwardly from the piston through a spring abutment I8 secured in the barrel. A disc I9 is secured on the piston rod rearwardly of the abutment I8, and a coiled compression spring 20 surrounds the rod between the abutment I8 and the piston I6 to drive the piston forwardly in the barrel. The slidable forearm I2 is connected to the piston rod and when moved in a direction toward the stock II, moves the rod I1 with the piston I6 and abutment washer I9 toward the stock, compressing the spring 20, until the abutment washer I9 is engaged by the trigger sear I5. When the trigger is then pulled, the spring drives the piston' I6 forwardly in the barrel and ejects a blast of compressed air from the muzzle end of the barrel. Forward travel of the piston is limited by engagement of the abutment washer I9 with the fixed abutment I 8 or with a resilient stop bearing against the fixed abutment.

As the gun maybe entirely conventional in construction and operation, a more detailed description is not considered necessary for the purposes of the present invention.

The powder dispenser of the invention comprises a tubular, cylindrical cartridge ZI which may be inserted into the muzzle end of the gun barrel I0, as illustrated in Figure 2, ahead of the forward position of the piston I6, or secured to the muzzle end of the barrel by a suitable socket or other convenient means. In the arrangement illustrated, the tubular cartridge 2| has an outside diameter substantially equal to the inside diameter of the gun barrel at the muzzle end of the latter, and a length substantially equal to the distance from the forward position of the piston I6 to the muzzle end of the gun barrel.

A piece of flexible, porous material 22 is disposed in the tubular cartridge 2I and extends from one end to the other of the latter. This piece of material 22 may conveniently be a piece of coarse woven cloth through which powder, such as talcum powder will filter, and in the form of the invention shown in Figures 2 to 5 inclusive, it takes the form of an elongated tube arranged substantially concentric with the tubular cartridge 2|. It may, however, be a piece of material of single thickness secured along its edges to the inner surface of the tubular cartridge, as illustrated in Figure 6.

The end of the tube 22, at the inner end of the tubular cartridge, that is, the end next to the piston I6, is secured to the cartridge by suitable adhesive and is reinforced by means of a ring 23 disposed within the end of the cartridge and compressing the corresponding end portion of the tube 22 between itself and the adjacent inner surface of the cartridge. The cartridge 2| and ring 23 may both be formed of a heavy paper or cardboard material for economy in manufacture.

The end of the tube 22 at the opposite or outer end of the cartridge is secured to the cartridge 3 by suitable adhesive, and reinforced by an annular nozzle 2t which may conveniently be formed of wood and is provided with a convergent, restricted orice 25 which is preferably concentric with the corresponding end of the cartridge 2l.

The space between the tube 22 of porous, exible material and the tubular cartridge 2| provides a storage space for powder 25 which powder lters at a slow r-ate through the tube y22'.

When the gun is operated, the piston I6 rapidly advances under force of spring 2B from its retracted position to its extended or forward position, as illustrated in Figure .2, fand in, 'doing so, forces a blast of compressed air through the interior of the tubular body 22 which air picks up powder from the inner surface of the tube `and forces the powder outwardly through the aperture 25 of the nozzle 2li, projecting a small cloud of powder at the muzzle end of the gun barrelr to simulate the smoke of gunpowder.

In the modi'ed arrangement 'show-n in vl"ig-ure e, the ring 23 :and nozzle 2i!v are 'prererably .retained and reinforce the connections between lthe ends of the bag fof lle'xi'bl'e, 'porous material the yend portions of the tubular, cylindrical cartridge 2i. The piece of material 22 may comprise a complete tubular structure, fas shown in Figure v2, the ends of which are brought together and secured in closed condition Vto the cartridge I', or may be a piece of materia-l of single thicknesses explainedabove.

vThe invention may be embodied in other s'p'ecic forms without departing from the spirit 'or essential characteristics thereof. The presen-t embodiments therefore, to be considered fall respects as illustrative and not restrictive, the scope of the invention being indicated by the lappended 'claims rather than by the foregoing description, and al1 changes which come within the meaning and range of equivalency iof the claims are, therevtore, intended tc be embraced therein.
